Where such execution is by a signer acting in a capacity other than such Person’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such Person’s authority.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. Any notice shall be effective when delivered (or, if mailed, three (3) Business Days after deposit, postage prepaid, in the first class U.S. mail and, if delivered by facsimile, upon completion of transmission and confirmation by the sender (by a telephone call to a representative of the recipient or by machine confirmation) that such transmission was received) provided that notwithstanding any other provisions set forth herein, any offer under Section 3.14 hereof shall be deemed received by a Holder when received by such Holder. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

In addition to the other provisions set forth in this Section 1.06, any notice or communication to a Holder of a Global Note may be made via electronic transmission (email or fax) or otherwise through the facilities of the Depository.

Section 3.08 Expiration of Restrictions

(a) Physical Notes. Any Physical Note (or any security issued in exchange or substitution therefor) that does not constitute a Restricted Note may be exchanged for a new Note or Notes of like tenor and aggregate Principal Amount that do not bear the Restricted Notes Legend required by Section 3.07.

(b) Global Notes.

(i) Promptly following the date that is one year after the Issue Date of any Option Notes, the Company shall use reasonable efforts to effect an exchange of every beneficial interest in each Restricted Global Note for beneficial interests in Global Notes that do not bear any Restricted Notes Legend. To effect such mandatory exchange, the Company will (A) deliver to the Depositary an instruction letter for the Depositary’s mandatory exchange process at least 15 days prior to the date set for such mandatory exchange (or such shorter time as may be permitted by the Applicable Procedures) and (B) deliver written notice to the Trustee and the Registrar (including, without limitation, by the Company’s delivery of an Officer’s Certificate to the Trustee for removal of the Restricted Notes Legend and authentication of one or more Unrestricted Global Notes (each, a “Free Transferability Certificate”) and an Opinion of Counsel to the effect that the Restricted Notes Legend may be removed from such Notes to be exchanged.

(c) If any Note, or any beneficial interest in a Global Note, is transferred by a Permitted Holder, in accordance with Sections 3.07 and 3.11 of this Indenture, to a Holder that is not a Permitted Holder, the new Note, or beneficial interest in a Global Note, issued to the transferee shall not bear the Purchase Agreement Legend and the transferee shall not be subject to the restrictions and conditions on transfer specified in the Purchase Agreement.

Section 3.09 Mutilated, Destroyed, Lost and Stolen Notes

(a) If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee or any agent from any loss which any of them may suffer if a Note is replaced, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 3.09, the Company may require payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Note issued pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

(b) Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Company, or an Affiliate of the Company, holds the Note.

If a Note is replaced pursuant to clause (a) of this Section 3.09, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced security is held by a protected purchaser.

The Company shall, on or before each due date of the principal of or interest on the Notes, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such principal or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided, however, that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by 11:00 a.m. New York City time, on such date.

(b) If the Company shall act as its own Paying Agent, it will, by 11:00 a.m. New York City time on each due date of the principal of or interest on the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal or interest so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the principal of or interest on the Notes when the same shall become due and payable.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

Section 4.05 Maintenance of Insurance

(a) Each Credit Party shall keep its insurable Property adequately insured at all times by financially sound and reputable insurers; maintain such other insurance, to such extent and against such risks as is customary with companies in the same or similar businesses operating in the same or similar locations, including insurance with respect to any Property subject to a Mortgage (including any insurance required under the Mortgage) and other properties material to the business of the Credit Parties against such casualties and contingencies and of such types and in such amounts with such deductibles as is customary in the case of similar businesses operating in the same or similar locations, including (i) physical hazard insurance on an “all risk” basis, (ii) commercial general liability against claims for bodily injury, death or property damage covering any and all insurable claims, (iii) explosion insurance in respect of any boilers, machinery or similar apparatus constituting Collateral, (iv) [Reserved], and (v) worker’s compensation insurance and such other insurance as may be required by any Legal Requirement; provided that if and so long as an Event of Default has occurred and is continuing with respect to physical hazard insurance, neither the Requisite Holders nor the applicable Credit Party shall agree to the adjustment of any claim thereunder in excess of $1,000,000 without the consent of the other (such consent not to be unreasonably withheld or delayed).

(b) The Credit Parties shall use commercially reasonable efforts to arrange for all of such insurance (and the corresponding insurance certificates) to provide that no cancellation, material reduction in amount or material change in coverage thereof shall be effective until at least thirty (30) days after receipt by the Collateral Trustee of written notice thereof (except with respect to cancellation as a result of a payment default, such cancellation shall not be effective until at least ten (10) days after receipt by the Collateral Trustee of written notice thereof) and if an endorsement providing such notice is commercially impracticable by any Credit Party’s carrier (or such carrier(s) otherwise refuse to deliver such notice), such Credit Party will use its commercially reasonable efforts to provide thirty (30) days or ten (10) days, as applicable, notice to the Collateral Trustee prior to the cancellation, material reduction in amount or material change in coverage. All such insurance (and the corresponding insurance certificates) shall (i) name the Collateral Trustee as mortgagee (in the case of property insurance) or additional insured on behalf of the Secured Parties (in the case of liability insurance) or loss payee (in the

case of property insurance), as applicable and (ii) be reasonably satisfactory in all other respects to the Requisite Holders (it being agreed that the amount, adequacy and scope of the policies of insurance of the Credit Parties in effect as of the Closing Date are acceptable to the Requisite Holders as of the Closing Date).

(c) If such Credit Party fails to obtain any insurance as required by this Section, the Collateral Trustee may obtain such insurance, acting at the direction of the Requisite Holders, at such Credit Party’s expense. By purchasing such insurance, neither the Collateral Trustee nor the Requisite Holders shall be deemed to have waived any Default or Event of Default arising from the Credit Party’s failure to maintain such insurance or pay any premiums therefor.

(d) With respect to Property subject to a Mortgage, each Credit Party shall obtain flood insurance in such total amount as the Requisite Holders or the Collateral Trustee (at the direction of the Requisite Holders) may from time to time reasonably require, if at any time the area in which any improvements located on any Property subject to a Mortgage is designated a “flood hazard area” in any Flood Insurance Rate Map published by the Federal Emergency Management Agency (or any successor agency), and otherwise comply with the National Flood Insurance Program as set forth in the Flood Disaster Protection Act of 1973, as amended from time to time.

(e) Promptly following the reasonable request of the Requisite Holders or the Collateral Trustee acting at the direction of the Requisite Holders, each Credit Party shall deliver to the Collateral Trustee and the Holders a report of a reputable insurance broker with respect to such Credit Party’s insurance and such supplemental reports with respect thereto as the Requisite Holders or the Collateral Trustee acting at the direction of the Requisite Holders, may from time to time reasonably request.

(f) No Credit Party shall knowingly take any action that is reasonably likely to be the basis for termination, revocation or denial of any insurance coverage required to be maintained under any Mortgage of any Credit Party or that could be the basis for a defense to any claim under any Insurance Policy maintained in respect of the Property subject to a Mortgage, and each Credit Party shall otherwise comply in all material respects with all Insurance Requirements in respect of the premises; provided, however, that the foregoing to the contrary notwithstanding, such Credit Party may, at its own expense and so long as it provides prompt written notice thereof to the Collateral Trustee, (i) contest the applicability or enforceability of any such Insurance Requirements by appropriate legal proceedings, the prosecution of which does not constitute a basis for cancellation or revocation of any insurance coverage required under this Section 4.05 or (ii) cause the Insurance Policy or any other insurance policy containing any such Insurance Requirement to be replaced by a new policy complying with the provisions of this Section 4.05 (and, after such new policy is in place, terminate the policy that is so replaced).

(c) Except as expressly permitted herein or in any other Equity Document or Indenture Document, each Credit Party shall (a) perform and observe all material terms and provisions of each contract, instrument, agreement or other document (after giving effect to all cure periods set forth therein), in each case, to the extent such contract, instrument, agreement or other document relates to Property, revenues or obligations of such Credit Party with value in excess of $1,000,000, to be performed or observed by it, (b) maintain each such contract, instrument, agreement or other document in full force and effect, and (c) enforce each such contract, instrument, agreement or other document in accordance with its terms provided, however, without limiting the other provisions set forth herein, (x) that no Credit Party shall be required to pay or perform any obligations (or enforce, observe and perform the terms of, or maintain in full force and effect, any agreement relating thereto) which are being contested in good faith, with respect to which reserves in conformity with GAAP have been provided and (y) no Credit Party shall be obligated to perform, observe, maintain, or enforce any such contract, instrument, agreement or other document if the failure to do so would not reasonably be expected to result in a Material Adverse Change.

(b) Each Credit Party shall timely and correctly file all Tax returns required to be filed by it, except where the failure to do so would not reasonably be expected to result in a Material Adverse Change.

(b) 144A Information. For so long as any of the Notes or shares of Common Stock delivered upon conversion of the Notes or in respect of any Make-Whole Payment will, at such time, constitute “restricted securities” under Rule 144 of the Securities Act, the Company will promptly provide to the Trustee and will, upon written request, provide to any Holder or beneficial owner of such Notes or such shares of Common Stock and any prospective purchaser of such Notes or such shares of Common Stock, the information required pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or such shares of Common Stock pursuant to Rule 144A under the Securities Act, and it will take such further action as any Holder or beneficial owner of such Notes or such shares of Common Stock may reasonably request from time to time to enable such Holder or beneficial owner to sell such Notes or such shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time.

(iv) the exercise and forbearance from exercise of all rights and remedies of a secured party under the UCC or any similar law of any applicable jurisdiction or equity.

Section 5.02 Authorization of Actions to Be Taken

(a) Each Holder of Notes, by its acceptance thereof, hereby designates and appoints the Collateral Trustee as its agent under this Indenture and the Security Documents and each Holder by acceptance of the Notes consents and agrees to the terms of each Security Document, as originally in effect and as amended, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Collateral Trustee to enter into the Security Documents, and irrevocably authorizes and empowers the Collateral Trustee to perform its obligations and duties, exercise its rights and powers and take any action permitted or required thereunder that are expressly delegated to the Collateral Trustee by the terms of this Indenture and the Security Documents, and consents and agrees to the terms of each Security Document, as the same may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms. The Collateral Trustee shall hold (directly or through any agent) and is directed by each Holder to so hold, and shall be entitled to enforce on behalf of the Holders all Liens on the Collateral created by the Security Documents for their benefit.

(b) Each of the Collateral Trustee and the Trustee is authorized and empowered to receive for the benefit of the Holders of Notes any funds collected or distributed under the Security Documents and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

(c) The Trustee shall provide to the Collateral Trustee a copy of each written notice of Default or Event of Default which the Trustee may receive under Section 11.03(i). Subject to Article 5 hereof, the Requisite Holders or the Trustee, pursuant to the direction of the Requisite Holders, shall direct the Collateral Trustee with respect to any action, omission, forbearance, enforcement or exercise of remedies with respect to the Collateral for purposes of any Enforcement Action. Unless receiving a contrary direction from the Requisite Holders, each of the Collateral Trustee and the Trustee is authorized and empowered to institute and maintain such suits and proceedings as it may deem expedient to protect or enforce the Liens securing the Obligations or to prevent any impairment of Collateral by any acts that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and proceedings as it may deem expedient to preserve or protect its interests and the interests of the Holders of Notes in the Collateral, including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Liens securing the Obligations or be prejudicial to the interests of Holders of Notes, the Collateral Trustee or the Trustee.

(d) The Collateral Trustee shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Credit Parties or is cared for, protected, or insured or has not been encumbered, or that the Collateral Trustee’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Credit Parties’ property constituting Collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, it being understood and agreed by the Credit Parties and the Holders that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Trustee shall have no other duty or liability whatsoever to the Trustee or any Holder or the Credit Parties as to any of the foregoing.

Section 5.03 Application of Proceeds of Collateral

Upon any realization upon the Collateral from the exercise of any rights or remedies under any Security Document or any other agreement with any Credit Party which secures any of the Obligations, the proceeds thereof shall be applied in accordance with Section 9.06 of this Indenture.

Section 5.04 [Reserved]

Section 5.05 Trust Indenture Act Requirements; Opinion of Counsel; Certificates of the Company

The Credit Parties shall furnish to the Collateral Trustee and the Trustee (a) upon the issuance of any Additional Notes (which, only for the purposes of this Section 5.05 shall exclude PIK Notes) and (b) at least thirty (30) days prior to the anniversary of the First Issue Date in each year, an Opinion of Counsel, dated as of such date, either (1) stating that, in the opinion of such counsel, (i) action has been taken with respect to the recording, registering, filing, re-recording, re-registering and re-filing of this Indenture, all supplemental indentures, all Security Documents, financing statements, continuation statements or notices, recordings or other instruments of further assurance as is necessary to maintain the Liens securing the Obligations and reciting the details of such action or referring to prior Opinions of Counsel in which such details are given, if applicable, and (ii) based on relevant laws as in effect on the date of such Opinion of Counsel, all financing statements, financing statement amendments and continuation statements have been executed and filed that are necessary as of such date and during the succeeding 12 months fully to preserve and perfect the Liens securing the Obligations, to the extent the Liens securing the Obligations can be perfected by the filing of a financing statement, and such Opinion of Counsel may contain customary qualifications and exceptions and may rely on an Officers’ Certificate (as to factual matters only); provided that if there is a required filing of a continuation statement or other instrument within such 12 month period and such continuation statement or amendment is not effective if filed at the time of the Opinion of Counsel, such Opinion of Counsel may so state and in that case the Credit Parties shall cause a continuation statement or amendment to be timely filed so as to maintain such Liens and security interests securing the Obligations; or (2) stating that, in the opinion of such counsel, no such action is necessary to maintain such Liens securing the Obligations as effective and perfected. The Credit Parties shall otherwise comply with the provisions of Trust Indenture Act § 314(b), including, for the avoidance of doubt the requirement to furnish to the Collateral Trustee and the Trustee promptly after the execution and delivery of this Indenture, an Opinion of Counsel stating that in the opinion of such counsel the Indenture (and/or any applicable filings) have been properly recorded and filed so as to make effective the Lien intended to be created thereby, and reciting the details of such action (see clause (1) above), or stating that in the opinion of such counsel no such action is necessary to make such Lien effective (see clause (2) above). In addition, to the extent applicable, the Credit Parties shall cause Trust Indenture Act § 313(b), relating to reports, and Trust Indenture Act § 314(d), relating to the release of property or securities from the Liens securing the Obligations or relating to the substitution therefor of any property or securities to be subjected to the Liens securing the Obligations, to be complied with. Any certificate or opinion required by Trust Indenture Act § 314(d) may be made by an officer of the Company, except in cases where Trust Indenture Act § 314(d) requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert reasonably satisfactory to the Trustee. The determination as to whether an independent Person needs to sign such certificate or opinion shall be made by the Company and neither the Trustee nor the Collateral Trustee shall have any responsibility related thereto. Notwithstanding anything to the contrary in this Article 5, the Company shall not be required to comply with all or any portion of Trust Indenture Act § 314(d) if it determines, in good faith based on advice of counsel, that under the terms of Trust Indenture Act § 314(d) and/or any interpretation or guidance as to the meaning thereof of the Commission or its staff, including “no action” letters or exemptive orders, all or any portion of Trust Indenture Act § 314(d) is inapplicable to one or a series of released Collateral.

(a) [Reserved]

(b) [Reserved]

(c) Notwithstanding anything to the contrary in this Indenture, the Notes, or in any Security Document (without limiting the provisions of the sentence immediately following this sentence), in no event shall the Collateral Trustee or the Trustee make any representation as to or be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the Security Documents (including without limitation the filing or continuation of any UCC financing statements, mortgages, security agreements or similar documents or instruments in any U.S. or foreign jurisdiction), nor shall the Collateral Trustee or the Trustee be responsible for, and neither the Collateral Trustee nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Security Documents or the security interests or Liens intended to be created thereby. If, at the direction of the Requisite Holders, the Trustee or Collateral Trustee files or records any Security Documents or any related UCC financing statement or other similar documents, such filing or recording by the Trustee or Collateral Trustee at the direction of the Requisite Holders shall be deemed done by Trustee or Collateral Trustee without representation or warranty by the Trustee or the Collateral Trustee (and the Trustee and the Collateral Trustee disclaim any representation or warranty as to the validity, effectiveness, priority, perfection or otherwise). Neither the Trustee nor the Collateral Trustee shall have any duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or any Security Document by the Company or any Credit Party or any other Person that is a party thereto or bound thereby.

Section 5.07 Release of Collateral.

(a) The Liens securing the Obligations on the applicable Collateral shall be automatically terminated and released without further action by any party (other than satisfaction of any requirements in the Security Documents, if any), in whole or in part: (i) upon any Disposition of any portion of Collateral in accordance with a Disposition permitted under the terms of any Indenture Document; (ii) upon payment in full of principal, interest and all other Obligations of the Company under the Notes issued under this Indenture; (iii) at the direction of the Requisite Holders or as otherwise may be required by the Security Documents; or (iv) if the Collateral is owned by a Guarantor, upon release of such Guarantor from the Guaranteed Obligations in accordance with the provisions hereof.

(b) Without the necessity of any consent of or notice to the Trustee or any Holder of the Notes, any Credit Party may request and instruct the Collateral Trustee to, on behalf of each Holder of Notes, (i) execute and deliver to any Credit Party, as the case may be, for the benefit of any Person, such release documents as may be reasonably requested, of all Liens held by the

101

Collateral Trustee in any Collateral securing the Obligations, and (ii) deliver any such assets in the possession of the Collateral Trustee to any Credit Party, as the case may be; and Collateral Agent shall promptly take such actions provided that any such release complies with the terms of this Indenture and the Security Documents and is accompanied by an Officers’ Certificate and Opinion of Counsel.

(c) The release of any Collateral from the Liens securing the Obligations or the release of, in whole or in part, the Liens securing the Obligations created by any of the Security Document will not be deemed to impair the Liens securing the Obligations in contravention of the provisions hereof if and to the extent the Collateral or the Liens securing the Obligations are released pursuant to the terms of this Indenture and the applicable Security Documents. Each of the Holders of the Notes acknowledges that a release of Collateral or Liens securing the Obligations strictly in accordance with the terms of this Indenture and the Security Documents will not be deemed for any purpose to be an impairment of the Security Documents or otherwise contrary to the terms of this Indenture.

ARTICLE 6

PAYMENTS FREE OF TAXES, ETC.

Section 6.01 Withholding

Any and all payments by or on account of any obligation of the Company under this Indenture shall to the extent permitted by Applicable Laws be made free and clear of and without reduction or withholding for any Taxes. If, however, Applicable Laws require any Tax to be withheld or deducted on any payments by or on account of any obligation of the Company under this Indenture, (i) the Company shall withhold or deduct such Tax in accordance with such Applicable Laws and timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with such Applicable Laws, and (ii) to the extent that the withholding or deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by the Company shall be increased as necessary so that after any required withholding or the making of all required deductions (including such deductions and withholdings applicable to additional sums payable under this Section 6.01) the Holder receives an amount equal to the sum it would have received had no such withholding or deduction been made.

Section 6.02 Other Taxes

Without limiting or duplicating the provisions of Section 6.01, the Company shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with Applicable Laws.

Section 6.03 Indemnification

The Company shall indemnify each Holder, within ten (10) days after written demand therefor delivered to the Trustee, for the full amount of any Indemnified Taxes or Other Taxes paid by such Holder or required to be withheld and deducted from a payment to such Holder, on or with respect to any payment by or on account of any obligation of the Company hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts

102

payable under this Article 6) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Company by a Holder shall be conclusive absent manifest error.

Section 6.04 Evidence of Payment

As soon as practicable after any payment of Taxes by the Company to a Governmental Authority as provided in this Article 6, the Company shall deliver to the Holders upon request the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of any return required by Applicable Laws to report such payment or other evidence of such payment reasonably satisfactory to the Holders.

Section 6.05 Forms

A Holder shall, at the time or times prescribed by Applicable Law or as reasonably requested by the Company, deliver such documentation prescribed by Applicable Law or reasonably requested by the Company as will enable to the Company to determine whether or not such Holder is subject to withholding, backup withholding and information reporting. Notwithstanding anything to the contrary in the immediately preceding sentence, the completion, execution, and submission of such documentation (other than such documentation set forth in the last two sentences of this Section 6.05) shall not be required if in the Holder’s reasonable judgment such completion, execution or submission would subject such Holder to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Holder. Without limiting the generality of the first sentence of this Section 6.05, a Holder that is not a “United States person” within the meaning of Section 7701(a)(30) of the Code (a “Non-U.S. Holder”) shall, to the extent legally entitled to do so, at the time it acquires the Notes and thereafter as reasonably requested by the Company or upon the expiration, invalidity or obsolescence of any previously delivered form, furnish to the Company: (a) two (2) accurate and complete originals of the applicable U.S. Internal Revenue Service Form W-8 and a certificate (substantially in the form of Exhibit D(1) or Exhibit D(2), as applicable) to the effect that the Holder (or its direct or indirect partners, as applicable) is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, is not a “10-percent shareholder” within the meaning of Section 881(c)(3)(B) of the Code and is not a controlled foreign corporation described in Section 881(c)(3)(C) of the Code, or (b) any other form prescribed by Applicable Law as a basis for claiming exemption from or reduction in U.S. federal withholding Tax together with such supplementary documentation as may be prescribed by Applicable Law to permit the Company to determine the withholding or deduction to be made. In addition, each Holder that is a “United States person” within the meaning of Section 7701(a)(30) of the Code shall, at the time or times prescribed by Applicable Law or as reasonably requested by the Company or upon the expiration, invalidity or obsolescence of any previously delivered form, furnish to the Company (a) two (2) complete and accurate originals of IRS Form W-9, or (b) any other form prescribed by Applicable Law as a basis for claiming exemption from backup withholding.

103

Section 6.06 Refunds

If any Holder determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to Article 6 (including by the payment of additional amounts pursuant to Section 6.01), it shall pay to the Company an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such Holder and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). The Company, upon the request of such Holder, shall repay to such Holder the amount paid over pursuant to this Section 6.06 (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such Holder is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 6.06, in no event will the Holder be required to pay any amount to the Company pursuant to this Section 6.06 the payment of which would place the Holder in a less favorable net after-Tax position than the Holder would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 6.06 shall not be construed to require any Holder to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Company or any other Person.

Section 6.07 FATCA

If a payment made to a Holder under any Note would be subject to U.S. federal withholding Tax imposed by FATCA if such Holder were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Holder shall deliver to the Company at the time or times prescribed by law and at such time or times reasonably requested by the Company such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Company as may be necessary for the Company to comply with their obligations under FATCA and to determine that such Holder has complied with such Holder’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.

Section 6.08 Survival

Without prejudice to the survival of any other agreement of the Company hereunder, the agreements and obligations of the Company contained in this Article 6 shall survive the payment in full of all amounts due hereunder.

ARTICLE 7

CONVERSION

Section 7.01 Right to Convert

(a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall have the right, at such Holder’s option, at any time commencing on June 20, 2017 until the Close of Business on the Business Day immediately preceding the Maturity Date, to convert the Principal Amount of any such Notes, or any portion of such Principal Amount, into shares of Common Stock, at the then Applicable Conversion Rate.

104

(b) Notwithstanding the foregoing, if a Holder has already delivered a Fundamental Change Purchase Notice with respect to a Note under Section 8.01, such Holder may convert such Note only if such Holder first withdraws the related Fundamental Change Purchase Notice pursuant to Section 8.03. If a Holder has surrendered such Holder’s Note for required purchase in connection with a Fundamental Change, such Holder’s right to withdraw the related Fundamental Change Purchase Note and convert each Note that is subject thereto will terminate at the Close of Business on (i) the Business Day immediately preceding the relevant Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Note, the Business Day immediately preceding the day on which such Default is no longer continuing.

(c) Provisions of this Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note.

(d) A Holder of Notes is not entitled to any rights of a holder of shares of Common Stock until such Holder has converted its Notes, and only to extent such Notes are deemed to have been converted into shares of Common Stock pursuant to this Article 7.

(e) [Reserved]

(f) During any period of time in which a Holder’s Beneficial Ownership of Common Stock is less than 5%, a Holder shall not have the right to convert all or any portion of the Principal Amount of any Notes into shares of Common Stock to the extent that upon and after giving effect to such conversion (and issuance of any shares of Common Stock in satisfaction of any Make-Whole Payment, as the case may be), such Holder (together with such Holder’s Affiliated Parties (including shares held by any “group” of which the Holder or any of its Affiliated Parties is a member)) would have Beneficial Ownership of more than 4.99% of the total number of shares of Common Stock then issued and outstanding (the “4.99% Ownership Limitation”); provided, that, such Holder may, at its option and upon not less than sixty-one (61) days’ prior notice to the Company, elect to increase the 4.99% Ownership Limitation to any other percentage not in excess of 9.99% of the number of outstanding shares of Common Stock then outstanding (the “9.99% Ownership Limitation”). Any such increase will not be effective until the 61st day after such notice is delivered to the Company. The Company hereby covenants and agrees not to adopt any shareholder rights plan or take any other action which would have the effect of restricting or adversely affecting the Holder’s election to change such threshold percentage. If at any time the Company shall be required under the Purchase Agreement or pursuant to the Indenture to issue shares of Common Stock to the Permitted Holders, but the issuance of such shares of Common Stock would exceed the ownership limitations set forth in this Section 7.01(f), in lieu of issuing such number of shares of Common Stock to the Permitted Holders in excess of the ownership limitations set forth in this Section 7.01(f), the Company shall issue to the Permitted Holders a New Warrant to acquire such shares of Common Stock pursuant to Section 4.18 of the Purchase Agreement. For avoidance of doubt, upon conversion of any Notes pursuant to this Indenture and issuance of shares of Common Stock or a New Warrant, as applicable, in connection with such conversion, such Notes shall be cancelled.

105

(g) For purposes of Section 7.01(f) above, “Beneficial Ownership” shall mean the number of shares of Common Stock beneficially owned by a Holder and its Affiliated Parties (and any other persons or entities acting as a “group” together with a Holder or any of such Holder’s Affiliated Parties) and shall include the number of shares of Common Stock issuable upon conversion of the Notes with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) conversion of the remaining, unconverted portion of the Notes beneficially owned by such Holder or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties) and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company exercisable for or convertible into Common Stock that are subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties). Except as set forth in the preceding sentence, for purposes of Section 7.01(f), Beneficial Ownership shall be calculated (and, for such purpose, whether any person or entity forms a “group” with any Holder or such Holder’s Affiliated Parties will be determined) in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher Beneficial Ownership for any such party, then such Beneficial Ownership will be calculated in accordance with Section 16 of the Exchange Act and the rules and regulations thereunder), it being acknowledged by each Holder that the Company is not representing to any Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and each Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that an ownership limitation contained in Section 7.01(f) applies, the determination of whether the Notes owned by a Holder are convertible (in relation to other securities owned by such Holder together with its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties)) and of which portion of the Notes owned by such Holder is convertible shall be in the sole discretion of such Holder, and the submission of a Conversion Notice to the Conversion Agent shall be deemed to be such Holder’s determination of whether the Notes owned by such Holder are convertible (in relation to other securities owned by such Holder together with any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties)) and of which portion of such Notes are convertible, in each case subject to the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, and neither the Company nor the Conversion Agent shall have any obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any “group” status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. In determining the number of outstanding shares of Common Stock the Holder may acquire upon the conversion of the Notes without exceeding the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K or other public filing with the Commission, as the case may be, (y) a more recent public announcement by the Company or (3) any other written notice by the Company or the

106

Transfer Agent setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company receives a Conversion Notice from a Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Conversion Notice would otherwise cause the Holder’s beneficial ownership, as determined pursuant to Section 7.01(f), to exceed the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, the Holder shall notify the Company of a reduced number of shares of Common Stock to be issued to such Holder upon the conversion of the Notes. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, by the Holder and the Holder’s Affiliated Parties since the date as of which the Reported Outstanding Share Number was reported.

(h) For the avoidance of doubt, if a Holder purports to convert the Principal Amount of any Notes into shares of Common Stock hereunder and any delivery otherwise owed to such Holder hereunder is not made, in whole or in part, as a result of the 4.99% Ownership Limitation, the 9.99% Ownership Limitation or any other limitation set forth in Section 7.01(a), and the Notes are not otherwise converted into a New Warrant pursuant to the Purchase Agreement, then the Holder’s rights under the relevant Notes pursuant to which such delivery was not made will not be extinguished and, instead such Notes will be deemed to have never been converted by such Holder. In the event that the issuance of Common Stock to the Holder upon conversion of the Notes results in the Holder and the Holder’s Affiliated Parties being deemed to beneficially own, in the aggregate, shares of Common Stock in excess of the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, the number of shares of Common Stock so issued by which the Holder’s and the Holder’s Affiliated Parties’ aggregate beneficial ownership exceeds 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio. For purposes of clarity, the shares of Common Stock issuable upon conversion of the Notes in excess of the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to convert the Principal Amount of any Notes pursuant to this Section 7.01 shall have any effect on the applicability of the provisions of this Section 7.01 with respect to any subsequent determination of exercisability.

Section 7.02 Conversion Procedure

(a) Each Note shall be convertible at the office of the Conversion Agent.

(b) In order to exercise the conversion right with respect to any interest in Global Notes, the Holder must complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay any transfer taxes or duties if required pursuant to Section 7.08. However, no service charge will be imposed

107

by the Company, the Trustee or the Registrar for any registration of transfer or exchange of Notes except in compliance with the below provisions governing exercise of conversion rights. In order to exercise the conversion right with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the Note (the “Conversion Notice”) or facsimile of the Conversion Notice and deliver such notice to a Conversion Agent, which action shall be irrevocable;

(ii) surrender the Note to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents; and

(iv) if required pursuant to Section 7.08, pay any transfer taxes or duties.

The date on which the Holder satisfies all of the applicable requirements set forth above is the “Conversion Date.” The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 7 on the Conversion Date for such conversion.

(c) On the second Business Day immediately following the Conversion Date, the Company shall issue and shall deliver to the converting Holder at the office of the Conversion Agent, a certificate or certificates for the number of full shares of Common Stock issuable in respect of such conversion in accordance with the provisions of this Article 7. In case any Notes of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered, without charge to such Holder, new Notes in authorized denominations in an aggregate Principal Amount equal to the unconverted portion of the surrendered Notes.

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) on the date on which the requirements set forth above in Section 7.02(b) have been satisfied as to such Notes (or portion thereof) and the Person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become, as of the Close of Business on the relevant Conversion Date that such Holder converted the Notes, the holder of record of the shares of Common Stock represented thereby.

(d) Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion Agent appointed by the Company) shall make a notation on such Global Note as to the reduction in the Principal Amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion Agent other than the Trustee.

Section 7.03 Settlement upon Conversion

(a) With respect to any conversion of Notes, if any, the Company shall, subject to the provisions of this Article 7, deliver to converting Holders, in respect of the Principal Amount of Notes being converted, a number of shares of Common Stock equal to the Applicable Conversion Rate, on the second Business Day immediately following the relevant Conversion Date, together with any applicable Make-Whole Payment in cash or in shares of Common Stock, as applicable, and cash in lieu of any fractional shares of Common Stock pursuant to Section 7.03(d).

108

(b) Upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest unless such conversion occurs between a Regular Record Date and the Interest Payment Date to which it relates and the converting Holder was the Holder on the relevant Regular Record Date.

(c) If Notes are converted after the Close of Business on a Regular Record Date for the payment of interest, Holders of such Notes at the Close of Business on such Regular Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date (including any outstanding PIK Interest) notwithstanding the conversion.

(d) The Company shall not issue fractional shares upon conversion of Notes (and on payment of any Make-Whole Payment in shares of Common Stock, as applicable). If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion (and on payment of any Make-Whole Payment in shares of Common Stock, as applicable) (and the number of fractional shares, if any, for which cash shall be delivered) shall be computed on the basis of the aggregate Principal Amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered (and the aggregate Make-Whole Payment to be paid in shares of Common Stock, if applicable). If any fractional share would be issuable upon the conversion of any Notes (and on payment of any Make-Whole Payment in shares of Common Stock, as applicable), the Company shall make payment of an amount in cash for the current market value of the fractional shares. The current market value of a fractional share shall be determined (calculated to the nearest 1/1000th of a share) by multiplying the Last Reported Sale Price of the Common Stock on the relevant Conversion Date by such fractional share and rounding the product to the nearest whole cent.

(e) By delivery to the Holder of the full number of shares of Common Stock, together with any applicable Make-Whole Payment in cash or in shares of Common Stock, as applicable, and any cash payment for fractional shares, issuable upon conversion, the Company will be deemed to satisfy in full its obligation to pay the Principal Amount of the Notes so converted, the applicable Make-Whole Payment, as applicable, and all accrued and unpaid interest to, but excluding, the Conversion Date.

(f) Each Holder who elects to convert any of its Notes at the Holder’s option will receive a payment (the “Voluntary Conversion Make-Whole Payment”) for the Notes being converted. The Voluntary Conversion Make-Whole Payment will be an amount equal to the aggregate amount of interest payments that would have been payable on such converted Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has been paid on the Notes or from the next succeeding Interest Payment Date if such conversion occurs after a Regular Record Date and on or before the next succeeding Interest Payment Date), through and including the Maturity Date (determined as if such conversion did not occur). The Company may settle the Voluntary Conversion Make-Whole Payment in cash or in shares of Common Stock, at the Company’s election, subject to the limitations described in Section 7.01(f). A Holder shall have the right prior to settlement to notify the Company that any

109

proposed settlement of the Voluntary Conversion Make-Whole Payment in shares of Common Stock would violate such limitations. To the extent that such limitations apply, the number of shares of Common Stock issuable upon conversion (and the associated Principal Amount of the Notes being converted) and in settlement of the Voluntary Conversion Make-Whole Payment shall be reduced proportionately so that the total number of shares issuable upon and after giving effect to such conversion and in settlement of the Voluntary Conversion Make-Whole Payment in shares of Common Stock shall not exceed such limitations. If the Company elects to pay the Voluntary Conversion Make-Whole Payment in shares of Common Stock, the Company will deliver to each Holder of converted Notes a number of shares of Common Stock at settlement equal to (i) the amount of the Voluntary Conversion Make-Whole Payment owed to such Holder and being paid in shares of Common Stock divided by (ii) the applicable Conversion Price. Delivery of such shares of Common Stock shall be made in the same manner as the delivery of shares in settlement of the conversion obligation under this Article 7. If the Company elects or, due to the limitations set forth herein, is obligated to pay the Voluntary Conversion Make-Whole Payment in cash, the Company shall, on the second Business Day immediately following the relevant Conversion Date, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such Voluntary Conversion Make-Whole Payment, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action. Within two (2) Business Days immediately following the Conversion Date, the Company shall send, or at the written request and expense of the Company have the Trustee send, a notice to the Holders specifying whether the Company has elected to settle the Voluntary Conversion Make-Whole Payment in cash or in shares of Common Stock (the “Voluntary Conversion Make-Whole Payment Notice”). If the Company gives the Voluntary Conversion Make-Whole Payment Notice, it shall also deliver a copy of such notice to the Trustee and Paying Agent. With respect to Physical Notes, such delivery shall be by first class mail, and with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the Depository.

Section 7.04 Adjustment of Conversion Rate

The Applicable Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs as described below, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes participate (other than in the case of a share split or share combination), at the same time and on the same terms as holders of shares of Common Stock, solely as a result of holding the Notes, in any of the transactions described in this Section 7.04, without having to convert their Notes, as if such Holders held a number of shares of Common Stock equal to the Applicable Conversion Rate in effect immediately prior to the adjustment thereof in respect of such transaction, multiplied by the Principal Amount of Notes held by such Holders.

(a) If the Company issues shares of Common Stock as a dividend or distribution on the Common Stock, or if the Company effects a share split or share combination of its Common Stock, the Applicable Conversion Rate will be adjusted based on the following formula:

110

CR₁

CR₀

OS₁

OS₀

where,

CR₀ =

the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or share combination, as applicable;

CR₁ =

the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date or immediately after the Open of Business on such effective date, as applicable;

OS₀ =

the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record Date or immediately prior to the Open of Business on such effective date, as applicable; and

OS₁ =

the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made pursuant to this Section 7.04(a) shall become effective immediately after the Close of Business on the Record Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 7.04(a) is declared but not so paid or made, or any such share split or combination is announced but the outstanding shares of Common Stock are not split or combined, as the case may be, the Applicable Conversion Rate shall be immediately readjusted, effective as of the date the Company’s Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Applicable Conversion Rate will be made (other than (i) as a result of a reverse share split or share combination or (ii) with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the immediately preceding sentence).

(b) If the Company distributes to all or substantially all holders of shares of Common Stock any rights, options or warrants entitling them for a period of not more than sixty (60) calendar days after the date of such distribution to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of such distribution, the Applicable Conversion Rate will be increased based on the following formula:

111

CR₁

CR₀

OS₀ + X

OS₀ + Y

where,

CR₀=

the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;

CR₁ =

the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date;

OS₀ =

the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record Date;

X =

the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y =

the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the distribution of such rights, options or warrants.

The foregoing increase in the Applicable Conversion Rate shall be successively made whenever any such rights, options or warrants are distributed and shall become effective immediately after the Close of Business on the Record Date for such distribution. If such rights, options or warrants are not so distributed, the Applicable Conversion Rate will be immediately decreased to the Conversion Rate that would then be in effect if such Record Date for such distribution had not been fixed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Applicable Conversion Rate shall be immediately decreased to the Conversion Rate that would then be in effect had the increase made for the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the two immediately preceding sentences).

In determining whether any rights, options or warrants entitle the holders of shares of Common Stock to subscribe for or purchase or exercise conversion rights for, shares of Common Stock at a purchase price less than such average of the Last Reported Sale Prices of Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, and in determining

112

the aggregate exercise or purchase price payable for such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable upon exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company’s Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities (the “Distributed Property”), to all or substantially all holders of shares of Common Stock, excluding:

(i) dividends or distributions of Common Stock or rights, options or warrants as to which an adjustment was effected pursuant to Section 7.04(a) or Section 7.04(b), as the case may be;

(ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 7.04(d); and

(iii) Spin-Offs to which the provisions set forth below in this Section 7.04(c) apply;

then the Applicable Conversion Rate will be increased based on the following formula:

CR₁

CR₀

SP₀

SP₀ - FMV

where,


CR₀ =		the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;

CR₁ =		the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date;

SP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV =		the fair market value (as determined by the Company’s Board of Directors) of the Distributed Property distributed with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution;

113

provided that if “FMV” as set forth above is equal to or greater than “SP₀” as set forth above, in lieu of the foregoing increase, adequate provision will be made so that each Holder of a Note shall receive on the date on which the Distributed Property is distributed to holders of the Common Stock, for the Principal Amount of the Notes, the amount and kind of Distributed Property that such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Applicable Conversion Rate on the Record Date for such distribution; provided further that if the Company’s Board of Directors determines “FMV” for purposes of the foregoing increase by reference to the actual or when-issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the average of the Last Reported Sale Prices of the Common Stock for purposes of determining “SP₀” as set forth above.

An increase in the Applicable Conversion Rate made pursuant to the immediately preceding paragraph shall become effective immediately after the Close of Business on the Record Date for such distribution. If such distribution is declared but not so paid or made, the Applicable Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the immediately preceding sentence).

With respect to an adjustment pursuant to this Section 7.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary, or other business unit or affiliate, of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the Spin-Off) on The New York Stock Exchange, The NASDAQ Capital Market, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors) (a “Spin-Off”), the Applicable Conversion Rate will be increased based on the following formula:

CR₁

CR₀

FMV₀ + MP₀

MP₀

where,

CR₀ =

the Applicable Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR₁ =

the Applicable Conversion Rate in effect immediately after the end of the Valuation Period;

FMV₀ =

the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of Common Stock applicable to one share of Common Stock (determined for purposes of the definition of “Last Reported Sale Price” as if such Capital Stock or similar equity interest were Common Stock) over the first ten consecutive Trading Day period after, and including, the effective date of the Spin-Off (the “Valuation Period”); and

MP₀ =

the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

114

The increase in the Applicable Conversion Rate under the immediately preceding paragraph will be determined as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect immediately after the Close of Business on the Record Date of the Spin-Off; provided that in respect of any conversion during the Valuation Period, references with respect to ten (10) consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date of such Spin-Off to, and including, the Conversion Date in determining the Applicable Conversion Rate. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Applicable Conversion Rate shall be immediately decreased, effective as of the date the Company’s Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the immediately preceding sentence).

For purposes of this Section 7.04(c) (and subject in all respect to Section 7.12), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 7.04(c) (and no adjustment to the Applicable Conversion Rate under this Section 7.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Applicable Conversion Rate shall be made under this Section 7.04. If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, is subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets or property, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Record Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Applicable Conversion Rate under this Section 7.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Applicable Conversion Rate shall be readjusted as if such rights, options or warrants had not

115

been issued and (y) the Applicable Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share of Common Stock redemption or purchase price received by a holder or holders of shares of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of shares of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Applicable Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 7.04(a), Section 7.04(b) and this Section 7.04(c), any dividend or distribution to which this Section 7.04(c) is applicable that also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 7.04(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 7.04(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 7.04(c) is applicable (the “Clause C Distribution”) and any adjustment to the Applicable Conversion Rate required by this Section 7.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any adjustment to the Applicable Conversion Rate required by Section 7.04(a) and Section 7.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Record Date” for the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record Date for the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Close of Business on such Record Date or immediately prior to the Open of Business on such effective date, as applicable” within the meaning of Section 7.04(a) or “outstanding immediately prior to the Close of Business on such Record Date” within the meaning of Section 7.04(b).

(d) If any cash dividend or distribution is paid or made to all or substantially all holders of shares of Common Stock, the Applicable Conversion Rate shall be increased based on the following formula:

CR₁

CR₀

SP₀

SP₀ - C

where,


CR₀ =		the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such dividend or distribution;

CR₁ =		the Applicable Conversion Rate in effect immediately after the Close of Business on the Record Date for such dividend or distribution;

SP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C =		the amount in cash per share the Company distributes to holders of shares of Common Stock.

116

The increase in the Conversion Rate under this Section 7.04(d) will become effective immediately after the Close of Business on the Record Date for such dividend or distribution. If such dividend or distribution is declared but not so paid or made, the Applicable Conversion Rate shall be immediately decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the immediately preceding sentence).

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for the Principal Amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for such dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock (excluding odd lots of shares of Common Stock), to the extent that the cash and fair market value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period immediately following, and including, the Trading Day next succeeding the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender offer or exchange offer, the Applicable Conversion Rate will be increased based on the following formula:

CR₁

CR₀

AC + (SP₁ x OS₁)

OS₀ x SP₁

where


CR₀ =		the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Trading Day next succeeding the Expiration Date;

CR₁ =		the Applicable Conversion Rate in effect immediately after the Close of Business on the Trading Day next succeeding the Expiration Date;

AC =		the aggregate fair market value of all cash and any other consideration (as determined by the Company’s Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;

OS₀ =		the number of shares of Common Stock outstanding immediately prior to the Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange offer);

OS₁ =		the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange offer); and

SP₁ =		the average of the Last Reported Sale Prices of Common Stock over the ten (10) consecutive Trading Day period immediately following, and including, the Trading Day next succeeding the Expiration Date.

117

The increase in the Applicable Conversion Rate under this Section 7.04(e) shall occur at the Close of Business on the 10th Trading Day immediately following the Trading Day next succeeding the Expiration Date but will be given effect immediately after the Close of Business on the Expiration Date; provided that in respect of any conversion within the 10 consecutive Trading Day period immediately following, and including, the Expiration Date, references to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Expiration Date to, and including, the Conversion Date in determining the Applicable Conversion Rate.

If the Company is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company is ultimately prevented by Applicable Law from effecting all or any portion of such purchases or all such purchases are rescinded, the Applicable Conversion Rate shall immediately be readjusted to the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that had been effected. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the Applicable Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the immediately preceding sentence).

(f) [Reserved]

(g) In addition to those Conversion Rate adjustments required by Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) and 7.04(e), and to the extent permitted by Applicable Law and subject to the applicable rules of NASDAQ Stock Market, LLC and, if applicable, any other securities

118

exchange on which the Company’s securities are then listed, the Company from time to time (i) may increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days if the Company’s Board of Directors determines that such increase would be in the Company’s best interest and (ii) may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of shares of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to this Section 7.04(g), the Company shall mail to Holders of record of the Notes a notice of the increase (in lieu of any notice otherwise required under Section 7.04(j) below) at least five (5) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(h) The Applicable Conversion Rate will not be adjusted, among other things:

(i) upon the issuance of any shares of Common Stock pursuant to any future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee or director benefit plan or program of the Company, or assumed by the Company, or any of the Company’s Subsidiaries;

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as of the date the Notes were first issued, except as set forth in Section 7.12;

(iv) for a change in the par value of the Common Stock; or

(v) for accrued and unpaid interest, and Additional Interest, if any.

(i) Adjustments to the Applicable Conversion Rate under this Article 7 shall be calculated to the nearest cent or to the nearest one-ten thousandth (1/10,000th) of a share of Common Stock. No adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at least 1% in the Applicable Conversion Rate. Any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, upon any conversion of the Notes (solely with respect to the Notes to be converted), the Company shall give effect to all adjustments that Company otherwise has deferred pursuant to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment.

(j) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have received

119

such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment became effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at such Holder’s latest address appearing in the Register, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(k) In any case in which this Section 7.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Notes converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 7.03.

(l) For purposes of this Section 7.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 7.05 Effect of Reclassification, Consolidation, Merger or Sale

In the case of (a) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination), (b) any consolidation, merger or combination or similar transaction involving the Company, (c) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the Company and its Subsidiaries, or (d) any statutory share exchange, in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at the effective time of the Merger Event, the Company shall execute with the Trustee a supplemental indenture permitted under Section 14.01 providing for the right to convert the Principal Amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such Merger Event. If such Merger Event causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Notes will be convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of shares of Common Stock that affirmatively make such an election. The Company shall notify Holders of the Notes of such weighted average as soon as practicable after such determination is made. The Company shall not become a party to any Merger Event unless its terms are consistent with the foregoing. For the avoidance of doubt, adjustments to the Conversion Rate pursuant to Section 7.04 do not apply to distributions to the extent that the right to convert the Notes has been changed into the right to convert into, or exchange for, Reference Property.

120

If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person.

When the Company executes a supplemental indenture pursuant to this Section 7.05, the Company shall promptly deliver to the Trustee (in addition to any other documents required under Section 14.03) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or assets that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall also cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section shall similarly apply to successive Merger Events.

Section 7.06 Adjustments of Prices

Whenever any provision of this Indenture requires a calculation of the Last Reported Sale Prices over a span of multiple days, the Company will make appropriate adjustments determined by the Company or its agents to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Record Date, effective date or expiration date, as the case may be, of the event occurs, at any time during the period during which such prices are to be calculated. Such adjustments will be effective as of the Ex-Dividend Date, Record Date, effective date or expiration date, as the case may be, of the event causing the adjustment to the Conversion Rate.

Section 7.07 Company’s Conversion Option

(a) The Company may, from time to time, at any time during the period commencing six (6) months after the First Issue Date and ending on the Close of Business on the Business Day immediately preceding the Maturity Date, elect to mandatorily require the Holders to convert some or all of the Notes at the then applicable Conversion Rate, if the Last Reported Sale Price of the Common Stock over any ten (10) consecutive Trading Days during such period equals or exceeds 150% of the then applicable Conversion Price (a “Conversion Event”) by sending, or at the written request and expense of the Company having the Trustee send, a notice (the “Conversion Event Company Notice”) within twenty (20) Trading Days of the Conversion Event and not more than thirty (30) Trading Days but not less than ten (10) Trading Days prior to the day selected by the Company on which the Notes will be converted pursuant to the Company’s conversion option (the “Company Conversion Date”; and the date such Company Conversion Notice is sent to the Holders in the manner herein provided, the “Company Conversion Notice Date”). If the Company gives such notice, it shall also deliver a copy of such Company Conversion Notice to the Trustee and Paying Agent. With respect to Physical Notes, such delivery shall be by first class mail, and with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the Depository.

121

Each Company Conversion Notice shall state:

(i) the Company Conversion Notice Date;

(ii) the aggregate principal amount of Notes to be converted;

(iii) that the Company Conversion Notice is being made pursuant to this Section 7.07;

(iv) the events causing the Conversion Event and the date(s) of the Conversion Event;

(v) the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate;

(vi) the Conversion Event Make-Whole Payment (as defined below), and whether the Company has elected to settle the Conversion Event Make-Whole Payment (as defined below) in cash or in shares of Common Stock;

(vii) the Company Conversion Date;

(viii) the name and address of the Paying Agent and the Conversion Agent; and

(ix) the procedures that Holders must follow to allow the Company to convert their Notes, including the place or places where Holders will be required to surrender the Notes.

The Company’s election of its conversion option hereunder must be made equally and proportionately with respect to any and all Notes duly issued hereunder (or, in the case of Global Notes, pursuant to Applicable Procedures that most nearly approximate a pro rata selection), and the Last Reported Sale Price of the Common Stock must equal or exceed 150% of the then applicable Conversion Price on both the date of the Company’s election and on the Company Conversion Date. Notwithstanding the Company’s election of its conversion option hereunder, the Holders shall not be required to convert to the extent such conversion would result in such Holders receiving more than 425,000 shares of Common Stock in any three (3) month period, and such conversion shall be subject to the limitations described in Section 7.01(f). In connection with the Company’s exercise of its conversion option under this Section 7.07, the Holders will receive upon conversion, in addition to and concurrently with the other consideration payable upon conversion under this Article 7, a payment (the “Conversion Event Make-Whole Payment”) for the Notes being converted in an amount equal to the aggregate amount of interest payments that would have been payable on such converted Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has been paid on the Notes or from the next succeeding Interest Payment Date if such conversion occurs after a Regular Record Date and on or before the next succeeding Interest Payment Date), through and including the Maturity Date (determined as if such conversion did not occur).

122

(b) The Company may settle the Conversion Event Make-Whole Payment in cash or in shares of Common Stock, at the Company’s election, subject to the limitations described in Section 7.01(f). A Holder shall have the right prior to settlement to notify the Company that any proposed settlement of the Conversion Event Make-Whole Payment in shares of Common Stock would violate such limitations. If the Company elects to pay the Conversion Event Make-Whole Payment in shares of Common Stock, the Company will deliver to each Holder of converted Notes a number of shares of Common Stock at settlement equal to (i) the amount of the Conversion Event Make-Whole Payment owed to such Holder and being paid in shares of Common Stock divided by (ii) the applicable Conversion Price. Delivery of such shares of Common Stock shall be made in the same manner as the delivery of shares in settlement of the conversion obligation under this Article 7. If the Company elects or, due to the limitations set forth herein, is obligated to pay the Conversion Event Make-Whole Payment in cash, the Company shall, on the second Business Day immediately following the relevant Company Conversion Date, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such Conversion Event Make-Whole Payment, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action.

(c) Notwithstanding the foregoing, the Company shall not be entitled to exercise its conversion option under Sections 7.07(a) and (b) hereof if (i) an Event of Default has occurred and is continuing, (ii) a Filing Failure, Effectiveness Failure or Maintenance Failure (as such terms are defined in the Registration Rights Agreement) or other event has occurred as a result of which sales of all of the shares of Common Stock to be issued under Sections 7.07(a) and (b) hereof cannot be made under an effective registration statement, (iii) the Company has not listed or caused to have quoted all of the shares of Common Stock to be issued under Section 7.07(a) and (b) hereof on the NASDAQ Stock Market, LLC and/or each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted, (iv) such exercise (which, for the avoidance of doubt, includes any related Make-Whole Payment) would otherwise violate Section 7.01(f) of this Indenture or the listing requirements or other rules or regulations of the NASDAQ Stock Market, LLC and/or each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted, or (v) a Fundamental Change has occurred or the Company has entered into any agreement to effect a Fundamental Change which remains in effect.

Section 7.08 Taxes on Shares Issued

Any issue of share certificates on conversions of Notes shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes or duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of shares in any name other than that of the Holder of any Notes converted, and the Company shall not be required to issue or deliver any such share certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

123

Section 7.09 Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental Requirements

(a) [Reserved]

(b) Upon the issuance of any Notes, including PIK Notes, and upon any adjustment to the Conversion Price, the Company shall reserve, if necessary, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock, to provide for the conversion of the Notes, subject to the limitations set forth in Section 7.01(f) and shall not issue such shares as are so reserved for any other purpose except to the extent that the Notes are otherwise retired pursuant to the terms of this Indenture.

(c) Before taking any action that would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such shares of Common Stock at such adjusted Conversion Price.

(d) Subject to the Section 7.09(b) above, the Company covenants that all shares of Common Stock that may be issued upon conversion of Notes or in settlement of a Make-Whole Payment in shares of Common Stock shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any lien or adverse claim.

Section 7.10 Responsibility of Trustee and Conversion Agent

The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 7. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 7.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 7.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 11.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

124

Section 7.11 Notice to Holders Prior to Certain Actions

In case:

(a) of any action by the Company that would require an adjustment to the Conversion Rate pursuant to Section 7.04 or 7.14;

(b) the Company shall authorize the granting to the holders of all or substantially all of the shares of Common Stock of options, rights or warrants to subscribe for or purchase any share of any class or any other options, rights or warrants; or

(c) of any recapitalization, reclassification, reorganization or change of the Common Stock (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger, combination or similar transaction involving the Company, or of the sale, lease or transfer of all or substantially all of the assets of the Company and the Company’s Subsidiaries, as an entirety, or any share exchange; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any Significant Subsidiary that is a Credit Party,

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder at such Holder’s address appearing on the list of Holders provided for in Section 3.06 of this Indenture, as promptly as practicable, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of shares of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (ii) the date on which such recapitalization, reclassification, reorganization, or change of the Common Stock, or consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of shares of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such recapitalization, reclassification, reorganization, change of the Common Stock, or consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Section 7.12 Shareholder Rights Plan

Each share of Common Stock issued upon conversion of Notes or in settlement of a Make-Whole Payment in shares of Common Stock pursuant to this Article 7 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the shares of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any shareholder rights agreement adopted by the Company, as any such agreement may be amended from time to time. Notwithstanding the foregoing, if prior to

125

any conversion such rights have separated from the Common Stock in accordance with the provisions of the applicable shareholder rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed, to all holders of the Common Stock, Distributed Property as described in Section 7.04(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 7.13 Company Determination Final

Any determination that the Company or its Board of Directors must make pursuant to this Article 7 shall be conclusive if made in good faith and in accordance with the provisions of this Article 7, absent manifest error, and set forth in a Board Resolution.

Section 7.14 Conversion Rate Reset by the Representative

(a) At its option, the Representative shall have the one-time right to reset the Conversion Rate (the “Reset Right”), upon any Equity Financing that occurs within and including the date that is 180 days after the First Issue Date (the “Reset Period”), in accordance with the following reset calculations:

(i) If the Representative elects to reset the Conversion Rate in connection with an Equity Financing completed within and including the date that is ninety (90) days after the First Issue Date, the Conversion Rate shall be reset to a number of shares of Common Stock equal to (A) $1 divided by (B) one hundred twenty-five percent (125%) of the New Issuance Price.

(ii) If the Representative elects to reset the Conversion Rate in connection with an Equity Financing completed ninety-one (91) days after the First Issue Date, but within and including the date that is 180 days after the First Issue Date, Conversion Rate shall be reset to a number of shares of Common Stock equal to (A) $1 divided by (B) one hundred thirty-five percent (135%) of the New Issuance Price.

(b) If an Equity Financing, in which the New Issuance Price is less than the Conversion Price in effect on the First Issue Date, occurs during the Reset Period, the Company shall cause to be mailed to the Representative, the Trustee and the Conversion Agent, if other than the Trustee, as promptly as practicable, but in any event within two (2) Business Days following the completion of the Equity Financing, notice (the “Equity Financing Notice”) containing: (i) a statement that the Equity Financing Notice is being furnished pursuant to this Section 7.14; (ii) the date of the Equity Financing; (iii) a description of the securities issued in the Equity Financing; (iv) the New Issuance Price; and (iv) the applicable Conversion Rate if the Representative elects to exercise the Reset Right with such Equity Financing.

(c) The Representative may exercise the Reset Right with respect to a particular Equity Financing during the Reset Period only if the Representative delivers a Reset Notice to the Company within five (5) Business Days of the Representative’s receipt of the Equity Financing Notice. The Company shall cause a copy of the Reset Notice to be mailed to the Trustee and the Conversion Agent (if other than the Trustee) as promptly as practicable, but in any event within two (2) Business Days following receipt of such Reset Notice.

126

(d) If the Representative elects to reset the Conversion Price in accordance with this Section 7.14, for the remainder of the Reset Period, the Company shall provide the Representative with an Equity Financing Notice at least two (2) Business Days prior to the commencement of any Equity Financing to be completed with a New Issuance Price below the then in effect Conversion Price. During the remainder of the Reset Period, the Representative shall have the right to consent to any Equity Financing with a New Issuance Price below the then in effect Conversion Price.

(e) For purposes of determining the “New Issuance Price” of shares of Common Stock in an Equity Financing under this Section 7.14, the following shall be applicable:

(i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Options is less than the Conversion Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Options for such price per share. For purposes of this Section 7.14(e)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Options” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Options, upon exercise of the Options and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Options less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such Options, upon exercise of such Options and upon conversion exercise or exchange of any Convertible Security issuable upon exercise of such Options. No further adjustment of the Conversion Rate shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Conversion Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 7.14(e)(ii) the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the issuance or sale

127

of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further adjustment of the Conversion Rate shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issuance or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Rate has been or is to be made pursuant to other provisions of this Section 7.14(e), no further adjustment of the Conversion Rate shall be made by reason of such issuance or sale.

(iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Conversion Rate in effect at the time of such increase or decrease shall be adjusted to the Conversion Rate, which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7.14(e)(iii), if the terms of any Option or Convertible Security that was outstanding as of the First Issue Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 7.14(e)(iii) shall be made if such adjustment would result in an increase of the Conversion Rate then in effect.

(iv) Calculation of Consideration Received. In case any Option is issued in connection with the issuance or sale of other securities of the Company, together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such Options and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued or sold for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company pursuant to the terms of such other securities of the Company, less (II) the Option Value of such Options; provided, that if the value determined pursuant to clause (y) above would result in a value less than the par value of the Common Stock, then the other securities issued or sold in such integrated transaction shall be deemed to have been issued or sold for the par value of the Common Stock. If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of Publicly Traded Securities, in which case the amount of consideration received by the Company will be the Last Reported Sales Price of such Publicly Traded Securities on the date of receipt of such Publicly

128

Traded Securities. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or Publicly Traded Securities will be determined jointly by the Company and the Representative. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Representative. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company. For purposes of this Section 7.14, “Option Value” means the value of an Option based on the Black-Scholes Option Pricing model obtained from the “OV” function on Bloomberg determined as of the day of the most recent Last Reported Sale Price of the Common Stock prior to the public announcement of the pricing of the applicable Option (or, if the pricing is not publicly announced, on the most recent Last Reported Sale Price of the Common Stock prior to the pricing of the applicable Option) and reflecting (i) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of the applicable Option as of the applicable date of determination, (ii) an expected volatility equal to 40%, (iii) an underlying price per share equal to the most recent Last Reported Sale Price of the Common Stock prior to the public announcement of the pricing of the applicable Option (or, if the pricing is not publicly announced, on the most recent Last Reported Sale Price of the Common Stock prior to the pricing of the applicable Option), (iv) a zero cost of borrow and (v) a 360-day annualization factor.

(f) If the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent (if other than the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment became effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at such Holder’s latest address appearing in the Register, within twenty (20) days after execution thereof, with a copy of such notice provided to the Trustee and the Conversion Agent (if other than the Trustee). Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(g) If the Representative elects to exercise its Reset Right in accordance with this Section 7.14, the Company shall not complete any subsequent Equity Financing within the Reset Period, without the prior written consent of the Representative.

129

ARTICLE 8

PURCHASE AT OPTION OF HOLDERS UPON A FUNDAMENTAL CHANGE

Section 8.01 Purchase at Option of Holders upon a Fundamental Change

(a) Generally. If a Fundamental Change occurs at any time prior to the Maturity Date of the Notes, then each Holder shall have the right, at such Holder’s option to require the Company to purchase any or all of such Holder’s Notes, on a date specified by the Company that is no earlier than the 20th and not later than the 35th calendar day following the date of the Fundamental Change Company Notice, subject to extension to comply with Applicable Law (the “Fundamental Change Purchase Date”), at a purchase price (the “Fundamental Change Purchase Price”) in cash equal to (i) 100% of the Principal Amount thereof, plus (ii) accrued and unpaid interest thereon to, but excluding, the Fundamental Change Purchase Date (provided, however, that if the Fundamental Change Purchase Date occurs after a Regular Record Date and on or prior to the Interest Payment Date to which it relates, the Company will pay accrued and unpaid interest to the Holder of record on such Regular Record Date) or, in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes, the day on which such Default is no longer continuing, plus (iii) an amount (the “Fundamental Change Make-Whole Payment”) equal to the aggregate amount of interest payments that would have been payable on such repurchased Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has been paid on the Notes or from the next succeeding Interest Payment Date if such conversion occurs after a Regular Record Date and on or before the next succeeding Interest Payment Date), through but not including the Maturity Date (determined as if such repurchase did not occur).

Purchases of Notes under this Section 8.01 shall be made, at the option of the Holder thereof upon:

(i) delivery to the Paying Agent of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth on the reverse of the Notes on or prior to the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with Applicable Law, which must specify:

(A) if the Notes are Physical Notes, the certificate numbers of the Holder’s Notes to be delivered for purchase;

(B) the portion of the Principal Amount of the Holder’s Notes to be purchased; and

(C) that the Holder’s Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture; and

(ii) delivery or book-entry transfer of the Notes to the Trustee (or other Paying Agent appointed by the Company) (together with all necessary endorsements) at any time on or prior to the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with Applicable Law, at the applicable Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to receipt by the Holder of the Fundamental

130

Change Purchase Price therefor; provided that such Fundamental Change Purchase Price shall be so paid pursuant to this Section 8.01 only if the Notes so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof in the related Fundamental Change Purchase Notice; provided that, if such Holder’s Notes are not Physical Notes, such Holder must comply with the Applicable Procedures.

Any purchase by the Company contemplated pursuant to the provisions of this Section 8.01 shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the Holder promptly following the later of the Fundamental Change Purchase Date or the time of the book-entry transfer or delivery of the Notes.

Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee (or other Paying Agent appointed by the Company) the Fundamental Change Purchase Notice contemplated by this Section 8.01 shall have the right to withdraw such Fundamental Change Purchase Notice (in whole or in part) at any time prior to the Close of Business on (i) the Business Day prior to the Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes, the Business Day immediately preceding the day on which such Default is no longer continuing, in either case, by delivery of a written notice of withdrawal to the Trustee (or other Paying Agent appointed by the Company) in accordance with Section 8.03 below.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

(b) Fundamental Change Company Notice. On or before the 20th day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of record of the Notes and the Trustee and Paying Agent a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof (a “Fundamental Change Offer”). With respect to Physical Notes, such delivery shall be by first class mail, and with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the Depository. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish such information on the Company’s website or through such other public medium as the Company may use at such time.

Each Fundamental Change Company Notice shall state:

(i) that the Fundamental Change Company Notice is being made pursuant to this Section 8.01 and that all Notes tendered will be accepted for payment;

(ii) the events causing the Fundamental Change;

(iii) the date of the Fundamental Change;

(iv) the last date on which a Holder may exercise the purchase right or withdraw their election;

131

(v) the Fundamental Change Purchase Price;

(vi) the Fundamental Change Purchase Date;

(vii) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(viii) if applicable, the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate;

(ix) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with Section 8.03;

(x) that any Note not tendered will continue to accrue interest in accordance with the terms of this Indenture;

(xi) the procedures that Holders must follow to require the Company to purchase their Notes, including that Holders electing to have any Notes purchased will be required to surrender the Notes; and

(xii) that Holders whose Notes are being purchased only in part will be issued new Notes equal in Principal Amount to the unpurchased portion of the Notes surrendered.

No failure of the Company to give the foregoing notices and no defect therein shall limit any Holder’s rights or affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 8.01.

Notwithstanding anything to the contrary in this Section 8.01 the Company will not be required to make a Fundamental Change Offer upon a Fundamental Change if a third party makes the Fundamental Change Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 8.01 and purchases all Notes properly tendered and not withdrawn under the Fundamental Change Offer (it being understood that such third-party may make a Fundamental Change Offer that is conditioned upon and prior to the occurrence of a Fundamental Change).

Notwithstanding anything to the contrary contained herein, a Fundamental Change Offer may be made in advance of a Fundamental Change, conditioned upon the consummation of such Fundamental Change, if a definitive agreement is in place for the Fundamental Change at the time the Fundamental Change Offer is made.

(c) No Payment During an Acceleration. Notwithstanding the foregoing, no Notes may be purchased by the Company at the option of the Holders pursuant to this Section 8.01 if the Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes).

132

(d) Payment of Fundamental Change Purchase Price. The Notes to be purchased pursuant to this Section 8.01, as well as the Fundamental Change Make-Whole Payment, shall be paid for in cash.

Section 8.02 Effect of Fundamental Change Purchase Notice

Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 8.01(a), the Holder of the Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in Section 8.03) thereafter be entitled to receive solely the Fundamental Change Purchase Price with respect to such Note. Such Fundamental Change Purchase Price shall be payable to such Holder promptly following the later of (a) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in Section 8.01(a) have been satisfied) and (b) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 8.01(a).

Section 8.03 Withdrawal of Fundamental Change Purchase Notice

(a) A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice prior to the Close of Business on (i) the Business Day immediately preceding the relevant Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes, the Business Day immediately preceding the day on which such Default is no longer continuing, specifying:

(A) the Principal Amount of the withdrawn Notes;

(B) if the Notes are Physical Notes, the certificate numbers of the withdrawn Notes; and

provided that, if such Holder’s Notes are not Physical Notes, such Holder must comply with the Applicable Procedures.

Section 8.04 Deposit of Fundamental Change Purchase Price

Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price, of all the Notes or portions thereof properly tendered pursuant to the Fundamental Change Purchase Notice that are to be purchased as of the Fundamental Change Purchase Date. The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this Section 8.04. If the Paying Agent holds money sufficient to pay the Fundamental Change

133

Purchase Price of any Note surrendered for purchase and not withdrawn in accordance with this Indenture as of the Close of Business on the Fundamental Change Purchase Date, then immediately following the Close of Business on the Fundamental Change Purchase Date, (a) any such Note will cease to be outstanding and interest will cease to accrue thereon on the Fundamental Change Purchase Date (whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent) and (b) all other rights of the Holder in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest (including Additional Interest, if any) upon delivery or book-entry transfer of such Note).

Section 8.05 Notes Purchased in Whole or in Part

Any Note that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes equal in principal amount to any unpurchased portion of the Note or Notes surrendered.

Section 8.06 Covenant to Comply With Securities Laws upon Purchase of Notes

In connection with any offer to purchase Notes under Section 8.01, the Company shall, if required:

(a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other of the tender offer rules under the Exchange Act that may then be applicable;

(b) file a Schedule TO or any other required schedule under the Exchange Act; and

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to purchase the Notes.

Subject to the requirements of any applicable abandoned property laws, regardless of who acts as Paying Agent, the Paying Agent shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon, held by them for the payment of the Fundamental Change Purchase Price; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 8.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date, then as soon as practicable following the Fundamental Change Purchase Date, the Paying Agent shall return any such excess to the Company.

The Trustee shall not be charged with knowledge of any Event of Default, except as provided in Section 11.03(i).

Section 9.02 Acceleration of Maturity: Waiver of Past Defaults and Rescission

(a) If an Event of Default (other than those specified in Sections 9.01(i) and 9.01(j) involving any Credit Party) occurs and is continuing, then and in every such case the Requisite Holders may, or the Trustee, at the written request of the Requisite Holders, shall, declare 100% of the Principal Amount plus accrued and unpaid interest on all the outstanding Notes (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment (and all other Obligations), to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by such Holders), and upon any such declaration such Principal Amount plus accrued and unpaid interest (and all other Obligations) shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 9.01(i) or Section 9.01(j) with respect to any Credit Party, 100% of the Principal Amount plus accrued and unpaid interest on all outstanding Notes (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment (and all other Obligations), will automatically become due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b) The Requisite Holders, by written notice to the Company and the Trustee, may (x) waive any past Default and its consequences and (y) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article 9 provided, rescind any such acceleration with respect to the Notes and its consequences, except, in each case, with respect to a Default described in Section 9.01(a), Section 9.01(b) or Section 9.01(c) (which, in each case shall require the approval of each Holder directly affected by such Default), or in respect of a covenant or provision hereof which under Article 14 cannot be modified or amended without the consent of the Holder of each outstanding Note affected, if:

(i) such rescission will not conflict with any judgment or decree of a court of competent jurisdiction; and

137

(ii) all existing Events of Default (other than the non-payment of any Principal Amount or interest or any other Obligation that became due solely by such declaration of acceleration) have been cured or waived.

Upon any such waiver, the Default which has been waived shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured, for every other purpose of the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 9.03 Additional Interest

If an Event of Default occurs and is continuing, if so elected by the Requisite Holders, in addition to ordinary interest payable pursuant to Section 4.01, the Company shall pay Additional Interest on the Notes, which shall accrue at the rate of 2.0% per annum of the Principal Amount of Notes outstanding for each day during the period from and including the date on which such Event of Default first occurs to and including the date on which such Event of Default has been cured or waived or ceases to exist. Additional Interest shall also mean all amounts, if any, payable pursuant to the Registration Rights Agreement. Any Additional Interest payable pursuant to this Section 9.03 will be payable in arrears on each Interest Payment Date following accrual in the same manner as ordinary interest is payable pursuant to Section 4.01. Notwithstanding the foregoing, the accrual and/or payment of such Additional Interest shall not preclude, forebear, waive or delay the rights of the Holders hereunder to accelerate the Notes as provided in Section 9.02 or to elect or exercise any other remedies available to them hereunder or under Applicable Law.

Section 9.04 Collection of Indebtedness and Suits for Enforcement by Trustee

The Company covenants that if a Default is made in the payment of the Principal Amount plus accrued and unpaid interest on the Maturity Date therefor or in the payment of the Fundamental Change Purchase Price and any Make-Whole Payment which is then due and payable in respect of any Note, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If an Event of Default occurs and is continuing, the Trustee, with the consent of the Requisite Holders, may, but shall not be obligated to, pursue any available remedy, including but not limited to an Enforcement Action as contemplated under Article 5 hereof, to collect the payment of the Principal Amount plus accrued but unpaid interest on the Notes (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment, and/or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or does not produce any of the

138

Notes in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 9.05 Trustee May File Proofs of Claim

In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under this Indenture and Applicable Law in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 11.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 9.06 Application of Money Collected

Any money collected by the Trustee pursuant to this Article or the Collateral Trustee pursuant to the Security Documents shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money to Holders, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee and the Collateral Trustee under Section 11.07;

SECOND: To the payment of the amounts then due and unpaid on the Notes for the Principal Amount, Fundamental Change Purchase Price, interest (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment and other Obligations, as the case may be, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes; and

THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

139

Section 9.07 Limitation on Suits

No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Notes, the Subsidiary Guarantees or for the appointment of a receiver or trustee, or for any other remedy hereunder unless (a) an Event of Default specified in Section 9.01(a), Section 9.01(b) or Section 9.01(c) occurs which directly affects such Holder or (b) the Requisite Holders shall have made written request to the Trustee or the Collateral Trustee to institute a proceeding in its own name as Trustee or Collateral Trustee hereunder and offered to the Trustee or Collateral Trustee, as applicable, security or indemnity satisfactory to it against any loss, liability or expense and the Trustee or the Collateral Trustee, as applicable, for seven (7) days after its receipt of such request and offer of security or indemnity has failed to institute any such proceeding. In the case of (a) in the immediately preceding sentence, Holders shall be entitled to, but shall not be obligated to pursue, any right or remedy that would otherwise be available to the Trustee or the Collateral Trustee under this Indenture. In the case of (b) in the immediately preceding sentence, the Requisite Holders shall be entitled to, but shall not be obligated to pursue, any right or remedy that would otherwise be available to the Trustee or the Collateral Trustee under this Indenture. Notwithstanding the forgoing, no one or more Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders (it being understood that neither the Trustee nor the Collateral Trustee has an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Section 9.08 Unconditional Right of Holders to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount (including the Fundamental Change Purchase Price or interest in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes, or any Fundamental Change Purchase Date, any other Obligation or otherwise, as applicable), any accrued and unpaid interest (including Additional Interest, if any), any Make-Whole Payment, and to convert the Notes in accordance with Article 7, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected without the consent of such Holder.

Section 9.09 Restoration of Rights and Remedies

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

140

Section 9.10 Rights and Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 3.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 9.11 Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 9.12 Control by Holders

The Requisite Holders may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or Collateral Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with Applicable Law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee will be entitled to indemnification from the Holders satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Section 9.13 Undertaking for Costs

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, in either case in respect of the Notes, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in Principal Amount of the outstanding Notes, or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount on any Note on or after the Maturity Date of such Note or the Fundamental Change Purchase Date.

Section 11.01 Duties and Responsibilities of Trustee

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

(b) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(i) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

(A) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and Applicable Law, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(B) in the absence of bad faith or willful misconduct on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts;

142

(iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the Requisite Holders at the time outstanding determined as provided in Section 1.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(c) If any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 11.02 Notice of Defaults

The Trustee shall give the Holders notice of any Default of which the Trustee has knowledge (as provided in Section 11.03(i)) within ninety (90) days after the occurrence thereof so long as such Default is continuing; provided, that (except in the case of any Default in the payment of Principal Amount of, or interest on, any of the Notes or Fundamental Change Purchase Price or a default in the delivery of the consideration due upon conversion), the Trustee shall be protected in withholding such notice if and so long as a committee of officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Notes.

(e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney (at the reasonable expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation);

(h) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;

(i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee from any Holder or any Credit Party, and such notice references the Notes and the Indenture (and in the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default or Event of Default exists); and

144

(j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

Section 11.05 Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes

Section 11.06 Monies to be Held in Trust

Subject to the provisions of Section 13.04, all monies and properties received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received.

Section 11.07 Compensation and Expenses of Trustee

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ, for which the Company has received an invoice with reasonably detailed documentation of any such expenses) except any such expense, disbursement or advance as may arise from its gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, liability, claim or expense incurred without gross negligence, willful misconduct

145

or bad faith on the part of the Trustee or such officers, directors, employees and agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises, including reasonable fees and expenses of legal counsel limited to one firm and, to the extent so required, one local counsel in each applicable jurisdiction. The obligations of the Company under this Section 11.07 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 9.01(i) or Section 9.01(j) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 11.10 Eligibility of Trustee

There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 11.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

146

This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act § 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act § 310(b).

Section 11.11 Resignation or Removal of Trustee

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the Holders of Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Company’s Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Holders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, subject to the provisions of Section 9.13, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 11.09 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 11.10 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Company’s Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 9.13, any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided, however, that if no successor Trustee shall have been appointed and have accepted appointment sixty (60) days after either the Company or the Holders has removed the Trustee, the Trustee so removed may petition at its own expense any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

147

(c) The Requisite Holders at the time outstanding may at any time remove the Trustee with or without cause and nominate a successor trustee which shall be deemed appointed as successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 11.11 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 11.12.

Section 11.12 Acceptance by Successor Trustee

Any successor trustee appointed as provided in Section 11.11 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 11.07, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 11.07.

No successor trustee shall accept appointment as provided in this Section 11.12 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 11.09 and be eligible under the provisions of Section 11.10.

Upon acceptance of appointment by a successor trustee as provided in this Section 11.12, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders of Notes at their addresses as they shall appear on the Register. If the Company fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 11.13 Succession by Merger, Etc.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 11.09 and eligible under the provisions of Section 11.10.

148

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 11.14 Preferential Collection of Claims

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of § 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in § 311(b), regarding the collection of the claims against the Company (or any such other obligor). A Trustee who has resigned or been removed shall be subject to § 311(a) to the extent indicated therein.

Section 11.15 Trustee’s Application for Instructions from the Company

Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

Section 11.16 Collateral Trustee

In acting as Collateral Trustee, the Collateral Trustee may rely upon, and shall be entitled to the benefits, rights, protections, immunities and indemnities of and to enforce, each and all of the rights, powers, immunities, indemnities and benefits of the Trustee under this Indenture including, without limitation, those set forth in this Article 11 as well as in Sections 1.02 and 1.03. The Collateral Trustee may resign or be removed, and the Collateral Trustee’s successor shall be appointed in the same manner as provided with respect to the Trustee under this Article 11 (for the avoidance of doubt, the provisions of Sections 11.11 and 11.12 of this Indenture shall

149

be interpreted to apply to the Collateral Trustee as if it was referenced therein in lieu of the Trustee). With respect to any deposit account control agreement to which the Collateral Trustee is a party, (i) notwithstanding the terms thereof (but without limiting the Credit Parties’ indemnification obligations hereunder and under the other Indenture Documents), the Collateral Trustee shall not be liable for, and Holders shall indemnify the Collateral Trustee in respect of, any settlement items, fees, expenses, charges, indemnity obligations or any other obligations pursuant to such deposit account control agreement other than to the extent satisfied from the assets of the Credit Parties then held by the Collateral Trustee pursuant to this Indenture and the other Indenture Documents and (ii) for the avoidance of doubt, in addition to the other rights, powers, immunities, indemnities and benefits that the Collateral Trustee may be entitled to pursuant to the immediately preceding sentence, prior to taking any action or omitting to take any action under any such deposit account control agreement, the Collateral Trustee may, in its sole discretion, require the Holders to offer to the Collateral Trustee security or indemnity satisfactory to it against any loss, expenses and liabilities which may be incurred therein or thereby.

ARTICLE 15

GUARANTEES OF NOTES

Section 15.01 Subsidiary Guarantees

Subject to this Article 15, each of the Guarantors hereby, jointly and severally, unconditionally guarantees, on a senior secured basis, as primary obligors and not as a surety, to each Holder (and its successors and assigns) of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes and/or the Obligations of the Company hereunder and thereunder, that:

(a) the principal of, and interest on, each of the Notes will be promptly paid in full when due, whether at stated maturity, by required prepayment, declaration, demand, by acceleration, upon repurchase or otherwise, and interest on the overdue principal of and (to the extent permitted by law) interest (including but not limited to any outstanding accrued but not yet capitalized PIK Interest, all outstanding capitalized PIK Interest and any Additional Interest, and any interest, fees, costs or charges that would accrue but for the provisions of Title 11 of the United States Code after any bankruptcy or insolvency petition under Title 11 of the United States Code) and any outstanding Make-Whole Payment on the Notes, and all other payment obligations of the Company to the Holders or the Trustee under this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and

155

(b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration, upon repurchase or otherwise (such obligations in clauses (a) and (b) being herein collectively called the “Guaranteed Obligations”).

Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Company.

The Guarantors hereby agree that their obligations hereunder shall be absolute, irrevocable and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of the Notes or this Indenture or any other agreement or instrument referred to herein or therein, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a surety or Guarantor. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantors hereunder which remain absolute, irrevocable and unconditional under any and all circumstances as described above:

(i) at any time or from time to time, without notice to the Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of this Indenture or the Notes, if any, or any other agreement or instrument referred to herein or therein shall be done or omitted;

(iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be amended in any respect, or any right under the Indenture, Notes, or any other agreement or instrument referred to herein or therein shall be amended or waived in any respect or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with;

(iv) any Lien or security interest granted to, or in favor of any Holder or the Trustee as security for any of the Guaranteed Obligations shall fail to be perfected; or

(v) the release of any other Guarantor.

Each Guarantor further, to the extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

156

If any Holder or the Trustee is required by any court or otherwise to return to the Credit Parties, or any custodian, Trustee or other similar official acting in relation to any Credit Party, any amount paid by any Credit Party to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of the obligations guaranteed hereby.

Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 9 hereof (and shall be deemed to have become automatically due and payable in the circumstances in said Article 9) for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such obligations as provided in Article 9 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

Section 15.02 [Reserved]

Section 15.03 Releases of Subsidiary Guarantees

The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released: (1) in connection with any Disposition (including by way of merger or consolidation) of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Credit Party, to the extent such sale is permitted hereunder or to the extent such Capital Stock constitutes Excluded Property; (2) upon the designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; (3) upon satisfaction and discharge of this Indenture in accordance with Article 13 or (4) upon payment of the Obligations in full in immediately available funds.

Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the conditions described in the foregoing clauses (1), (2), (3) or (4) has occurred, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest, premium, and Additional Interest, if any, on, the Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 15.

Further, the Subsidiary Guarantees are not convertible and will automatically terminate when the Notes are all converted in full in accordance with Article 7 (including any Make-Whole Payment, which shall be paid or converted in accordance with Article 7).

157

Section 15.04 Instrument for the Payment of Money.

Each Guarantor hereby acknowledges that the guarantee in this Article 15 constitutes an instrument for the payment of money, and consents and agrees that any Holder (to the extent that the Holder is otherwise entitled to exercise rights and remedies hereunder) or the Trustee, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213 to the extent permitted thereunder.

Section 15.05 Limitation on Guarantor Liability

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of any bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee.

12.0% Convertible Senior Secured Notes due 2020

This Note is one of a duly authorized issue of Notes of the Company, designated as its 12.0% Convertible Senior Secured Notes due 2020 (the “Notes”), issued or to be issued under and pursuant to an Indenture dated as of June 20, 2017 (the “Indenture”) among the Company, the guarantors named on the signature pages thereof (the “Guarantors”), and Wilmington Savings Fund Society, FSB, as Trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Guarantors and the Holders of the Notes. The Indenture provides that Additional Notes may be issued thereunder, if certain conditions are met.

(1) Interest. The Notes will bear interest at a rate of 12.0% per year. Pursuant to Section 9.03 of the Indenture, in certain circumstances, the Holders of Notes shall be entitled to receive Additional Interest. Interest on the Notes will accrue from, and including, the Issue Date, or from the most recent date to which interest has been paid or duly provided for to, but excluding the next scheduled Interest Payment Date until the Maturity Date. Interest will be payable quarterly in arrears on each Interest Payment Date, beginning with the first Interest Payment Date which occurs after the Issue Date, in cash, provided, that if no Event of Default has occurred and is continuing under the Notes, interest at a rate of 10.0% per year will be payable on such Interest Payment Date in cash, and interest at a rate of 2.0% per year will be payable on such Interest Payment Date, either (i) by increasing the Principal Amount of the Notes, (ii) by issuing PIK Notes (“PIK Interest”) or (iii) by paying such interest on the Interest Payment Date in cash, at the Company’s option. Notwithstanding the proviso in the foregoing sentence, (i) interest on the first Interest Payment Date after the First Issue Date will be payable only in cash, and (ii) if the Initial Holders elect to exercise the option under the Purchase Agreement to purchase any Option Notes on or after the first Interest Payment Date after the First Issue Date, interest on the second Payment Date after the First Issue Date will be payable only in cash. The Company shall deliver a written notice to the Trustee and the Holders not less than five (5) Business Days prior to the relevant Interest Payment Date, which notice shall state the total amount of interest to be paid on such Interest Payment Date, the total amount of accrued PIK Interest as of such Interest Payment Date, and directing the Trustee on or prior to such Interest Payment Date to either issue PIK Notes or increase the Principal Amount of this Note on such date, in either case in amount equal to the amount of the accrued PIK Interest. PIK Interest on the Notes will be payable by increasing the Principal Amount of the Notes by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest whole dollar) (or, if necessary, pursuant to the requirements of The Depository Trust Company or its nominee, as the case, to authenticate new Global Notes executed by the Company with such increased Principal Amount of the Notes). Following an increase in the Principal Amount of the Notes as a result of a PIK Payment, the Notes will bear interest on such increased Principal Amount from and after the date of such PIK Payment.

170

Interest will be paid to the Person in whose name a Note is registered at the Close of Business on the March 15, June 15, September 15 and December 15 (whether or not such date is a Business Day), as the case may be, immediately preceding the relevant Interest Payment Date. Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

(2) Ranking and Security. The Notes are secured, equally and ratably, by a senior security in the Collateral pursuant to the Security Agreement and the Security Documents referred to in the Indenture. The Notes are secured by a pledge of Collateral pursuant to the Security Documents.

(3) Guarantees. The payment by the Company of the principal of, interest and Additional Interest, if any, on the Notes is fully and unconditionally guaranteed on a joint and several senior secured basis by each of the Guarantors to the extent set forth in the Indenture.

(4) No Optional Redemption. The Notes are not redeemable at the option of the Company prior to their stated maturity date. No sinking fund is provided for the Notes.

(5) Purchase at the Option of the Holder Upon a Fundamental Change. Subject to the terms and conditions of the Indenture, the Company shall become obligated, at the option of the Holder, to repurchase the Notes if a Fundamental Change occurs at any time prior to the Maturity Date at (i) 100% of the Principal Amount together, plus (ii) accrued and unpaid interest to, but excluding, the Fundamental Change Purchase Date (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest), plus (iii) the Fundamental Change Make-Whole Payment, which aggregate amount will be paid in cash.

(6) Withdrawal of Fundamental Change Purchase Notice. Holders have the right to withdraw, in whole or in part, any Fundamental Change Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. The right to withdraw the Fundamental Change Purchase Notice will terminate at the Close of Business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date.

(7) Payment of Fundamental Change Purchase Price. If money sufficient to pay the Fundamental Change Purchase Price of all Notes or portions thereof to be purchased on a Fundamental Change Purchase Date is deposited with the Paying Agent on the Fundamental Change Purchase Date, such Notes will cease to be outstanding and interest will cease to accrue on such Notes (or portions thereof) immediately after the Close of Business on such Fundamental Change Purchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Fundamental Change Purchase Price, upon surrender of such Note).

171

(8) Conversion. Subject to and upon compliance with the provisions of the Indenture (including without limitation the conditions of conversion of this Note set forth in Article 7 thereof), the Holder hereof has the right, at its option, to convert the Principal Amount hereof or any portion of such principal which is at least $1,000 into shares of Common Stock at the Applicable Conversion Rate. The Conversion Rate is initially 1.3589 shares of Common Stock per $1 Principal Amount of Notes (equivalent to an initial Conversion Price of approximately $0.7359), subject to adjustment in certain events described in the Indenture. Upon conversion, the Company will deliver shares of Common Stock and the Voluntary Conversion Make-Whole Payment, all as set forth in the Indenture (which may be paid in cash or shares of Common Stock). No fractional shares will be issued upon any conversion, but a payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Notes for conversion. Notes in respect of which a Holder is exercising its right to require repurchase on a Fundamental Change Purchase Date may be converted only if such Holder withdraws the related election to exercise such right in accordance with the terms of the Indenture. Subject to and upon compliance with the provisions of the Indenture (including without limitation the conditions of conversion of this Note set forth in Article 7 thereof), the Company may elect to require the Holder to convert some or all of the Notes if a Conversion Event occurs. Upon such conversion, the Company will deliver shares of Common Stock and the Conversion Event Make-Whole Payment, all as set forth in the Indenture (which may be paid in cash or shares of Common Stock).

In the event of a deposit or withdrawal of an interest in this Note, including an exchange, transfer, repurchase or conversion of this Note in part only, the Trustee, as custodian of the Depository, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depository.

(9) Acceleration of Maturity. Subject to certain exceptions in the Indenture, if an Event of Default shall occur and be continuing, the Principal Amount plus interest through such date on all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

(10) Supplemental Indentures with Consent of Holders; Waiver of Past Defaults. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of the Requisite Holders. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate Principal Amount of the outstanding Notes, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences.
